How to Create and Use Binocular Rivalry
Published on: November 10, 2010
Binocular vision: two possible central interactions between signals from two eyes.
Science (New York, N.Y.)
|May 7, 1976
Summary
Binocular vision’s detectability of light stimuli does not follow energy or probability summation rules. Instead, independent neural mechanisms likely process the sum or difference of signals from each eye.
Area of Science:
- Visual neuroscience
- Human sensory perception
- Ophthalmology
Background:
- Understanding binocular interaction is crucial for visual perception.
- Existing models like energy and probability summation have limitations in explaining certain visual phenomena.
Purpose of the Study:
- To investigate the summation rules governing binocular interaction in human vision.
- To challenge existing hypotheses of binocular summation.
- To propose alternative neural mechanisms for binocular signal processing.
Main Methods:
- Simultaneous stimulation of both foveae with monocular lights of varying luminance.
- Subjects judged the detectability of combined stimuli.
- Comparison of observed results with predictions from energy and probability summation models.
Main Results:
- The detectability of combined stimuli violated predictions of both energy and probability summation hypotheses.
- Observed binocular interaction patterns suggest a different underlying neural process.
Conclusions:
- Binocular interaction in light detection is not explained by simple summation models.
- Independent central neural mechanisms, potentially signaling stimulus sums or differences, better explain the observed results.

01:24Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:26Visual System
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

01:24Color Vision
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
01:20Parallel Processing
The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...
